Uniden TRU8885 Register/Deregister Issue

I purchased a used receiver that had not been deregistered. I tried using it on my original phone and it did not work. It seems that I cannot deregister the newly purchased receiver unless I had the base that came with it.

Re: Uniden TRU8885 Register/Deregister Issue

Here's what you do:

  • pull the battery
  • hold down * and # while reinserting battery
  • wait for beep
  • hit rightmost soft button (keys at top under the lcd screen)
  • wait for 'erase complete' message
  • hit end
Should work like a charm.

Handset deregister uniden

Don't "deregister" the one you are not using.
Just go ahead and register the new one.

The "END" and "#" key combination can be used for several purposes:

1) If wanting to use an ALREADY REGISTERED HANDSET on an alternate base, and if if the INITIAL BASE isn't available to deregister the handset:

1a) Press "END" + "#" until it for 5+ seconds (wait for it to beep)
1b) Choose the "Base Unavailable" option
1c) That'll deregister the CURRENT HANDSET so that it can be re-registered on ANY base.

2) If a BASE has a handset registered to it which you no longer want registered but the registered handset is missing or broken:

2a) Grab another WORKING handset which is properly REGISTERED to the BASE in question
2b) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)
2c) Choose the "Deregister HS" menu option
2d) Pick the REGISTERED HANDSET # to de-register. (Every other registered handset EXCEPT THE ONE YOU'RE ON will appear in the list!)

Deregister lost or broken phones

Some tricks from a helpful Uniden rep:

holding down end+# keys at the same time on the phone for about 10 secs (you will hear a beep) will deregister the handset. If you have a dead handset and want to deregister it from the base, you have to reset the base. unplug the phoneline and power. hold down the "delete message" key, plug power back in. about 10 secs later, you will hear a long beep (theres a short beep upon powerup as well). At this point all handsets are deregistred and you will have to reregister them with the end+# trick. this way when #1 handset is dead, you can make a working one #1 and get the broken one fixed emotion-1.gif

BTW, this is a woot warranty, not uniden warranty. however the uniden rep gave me the number to the people who refurb (rox0rz!) these. I'll post an update when I finally get ahold of them (and the number if its actually helpful)

OU might need to deregister the hand set first by holding down the red end (hang up key) and keep it down while holding the # key. If deregister wont work use base unavailable and yes, you are sure twice.

confirmation tone.

Cannot register handsets

I was having the same problem, and ended up putting each handset in the main base station to register.

Register additional handsets on a Uniden phone

From: Uniden Customer Support

On most models you can find an option in the menu for De-register? In that case you would select that option and select to deregister the handset.
TRU88 models you go to the main menu and go to De-register HS select yes to deregister the Handset.

DCT5 and DCT6 models: Press menu on the handset. Go to System Reset and Press select. Go to Deregister HS and press select. Arrow up to yes and press select. Then go back into the menu. Go to system reset and press select. Arrow down to Replacing the base and press select. Arrow up to yes and press select.

DCT7 models: Press and hold "end" and "#" until the system reset menu appears on the display. Then follow the instructions from above for the DCT5 and DCT6 deregister procedures once your into the menu.

TRU4 and TRU5 models: Press and hold xfer/del and end until "de-register?" appears. Use the plus+ button to go up to yes and press select.

To register any of the following phones please see you owners manual under either:

•Register handset or

Deregistering a phone you can't find

I had trouble deregistering one of the phones, as it has to be close to the original base (kept telling me out of range). I found out that pressing END and #, also deregisters.

This sounds like the register-deregister problem elsewhere on this page. Try holding down the "end" and "#" buttons for about 6 seconds to deregister the phones and then reregister them. I had this problem too and it worked for me.
